BINDER COMPOSITION FOR NONAQUEOUS SECONDARY CELL, SLURRY COMPOSITION FOR NONAQUEOUS SECONDARY CELL FUNCTIONAL LAYER, FUNCTIONAL LAYER FOR NONAQUEOUS SECONDARY CELL, CELL MEMBER FOR NONAQUEOUS SECONDARY CELL, AND NONAQUEOUS SECONDARY CELL

摘要

The purpose of the present invention is to provide a binder composition for a nonaqueous secondary cell, said binder composition allowing preparation of a slurry composition for a nonaqueous secondary cell functional layer, said slurry composition having excellent viscosity stability. A binder composition for a nonaqueous secondary cell according to the present invention contains a polymer, bacteria, and water. The mean size of the bacteria is 0.5 μm or less.
